Selecting the Kc Factor
When the [Kc] menu cell is selected, the meter imposes this % slope adjustment of its rate
output. Output data is zeroed and corrected for the Reynolds number (flow profile compensated), however, in addition, a percent change in the rate output is imposed based on the data
entered in this cell. The number entered by the user is evaluated into a slope correction factor
by dividing it by 100 and algebraically adding it to 1. The resulting factor is used as a multiplier on the rate register of the instrument. Thus an entry of -3% will multiply the rate register by 0.97, for example.
To calculate Kc:
Kc =

To enter the Kc Factor:
To enable numeric entry press
.
Use the numeric keys to type the required Kc (as calculated above). Note that the Kc
value can be negative or positive. Enter the - or + sign first, then type in the calibrated
value.
To store the data press ENT . Note that Kc now appears in the right-hand column of the
[Calibrate Flow Rate] menu cell with its new value. Also note that this Kc value can be
viewed on the site printout.
Calibration Tables 1 through 3
System 1010 instruments offer a unique methodology by which a particular flow response of
an instrument may be linearized or optimized by tabulating the results of a series of calibration exercises or collected batch data points. In essence, the meter allows the user to select
any of a wide variety of system variables (flowrate, pressure, viscosity, etc.) as a pointer into a
table of calibration factors (up to 32). As the system variable is updated, the value of the table’s
